Parts of the Baltimore region were under a flood warning Saturday night as multiple inches of rain fell across central Maryland, the National Weather Service said.

The flood warning was in effect from around 6:30 p.m. Saturday to 12:30 a.m. Sunday for much of the Central Maryland region, including Baltimore City, according to the weather service. Earlier in the day, meteorologists had warned of flooding at the end of Thames Street in Fells Point and along the Inner Harbor promenade near the dragon boat dock. Minor flooding was also expected near Bowley’s Quarters, the weather service said.

By the evening, “stream gauges indicate rising water levels across the area,” the weather service announced. “Additional flooding is possible in areas of poor drainage.”

Heavy rains led to traffic delays as the water halted cars on major roads. Around 7 p.m., the Maryland Transportation Authority announced that the MD 295 ramp onto I-95 was blocked because of high water. Their Twitter feed was full of rain-related alerts about lane closures Saturday evening.

The rain came after the region saw sleet and freezing rain earlier Saturday. Central and Western Maryland were under a winter weather advisory Saturday morning, and Allegany County in Western Maryland was under a winter storm warning for freezing rain and sleet through Saturday afternoon.

The weather service did not include Ellicott City on the list of cities that might see flooding. The Howard County town was devastated by a deadly flood earlier this year. The county’s fire department tweeted that it was “getting reports of flooded roadways” and urged people to avoid the roads.

“Turn around, don`t drown when encountering flooded roads,” the service said. “Be especially cautious at night when it is harder to recognize the dangers of flooding.”

Rain was expected to continue through Saturday night as precipitation totals climbed for Baltimore’s wettest year on record. Things should warm up a bit come Sunday, with mostly sunny conditions and a high of 56 degrees expected.
